CATALYST UNLOADING FROM PIPE REACTORS Russian patent published in 2019 - IPC B01J8/00 B01J8/06 

FIELD: transportation.

SUBSTANCE: invention relates to unloading of catalyst from pipe reactors, in particular, to device and method of unloading of disperse material, such as particles of spent catalyst, from reactor tubes of catalytic reactor. Device comprises air lance for loosening of disperse material inside reactor tube using compressed air, unit of air lance for introduction of air lance into reactor tube and discharge from it, and flexible guide pipe, which at one end is detachably connected to the air peak unit, and at the other end is connected to the first cleaned reactor tube, to direct the air peak from the reactor pipe through the air peak unit to the first cleaned reactor tube, to place part of air peak, which was not introduced into reactor tube, inside first cleaned reactor tube, wherein first cleaned reactor tube is a reactor tube, which was unloaded and / or cleaned before discharge of disperse material from reactor tube.

EFFECT: invention makes it possible to remove disperse material from reactor tubes economically with respect to labor inputs and time by means of.
